PROCÉDÉ POUR COMMANDER UNE OPPORTUNITÉ DE TRANSMISSION ET DISPOSITIF ASSOCIÉ

摘要

An access point sends a first frame. The first frame carries a TXOP handover enforcement THE indication field which is a first value or a second value. The first value is used to instruct a station that has accessed a channel to hand over a held TXOP to the access point, and the second value is used to instruct the station that has accessed the channel to hand over the held TXOP to the access point when a handover condition is satisfied. It can be learned that the STA hands over the held TXOP to the AP. Therefore, the AP may be a TXOP holder through the TXOP handover even if the AP fails to obtain the channel through contention, so that a probability of holding the TXOP by the AP is improved, a probability of scheduling a STA by the AP is improved, and system resource utilization is improved.
